CONTINUOUS TRAVELING TABLE.

JPECIFICATION forming part of Letters Patent No. 720,149, dated February10, 1903.

Application filed February 28, 1902. Serial No. 96,184. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN INGLEBY, a subject of the King of Great Britainand Ireland, d c resident of Leeds, in the county of York,

nd,have invented a certain new and use- .nprovement in ContinuousTraveling Tas, of which the following is a specication. Ihe crifct ofthis invention is to combine 'fes of continuity of action ob- ;ained.ss-rolls, calendering-machines, and other rotary presses Without thedisad- 'antage that these possess in certain cases of oft or plasticmateu'al in that the material s caused to flow backward, and is thusreduced in thickness by-removal of the material instead of byconsolidation. In certain cases-as, for example, in the man ufacture ofY the pattern or design u inlaid linoleums, in which it is desired tokeep "ized through the ull thickness of the rn.V t -such presses -annotbe used andthe .siaterial is usually .onsolidated by ordinary fiatpresets acting icc-ssively on dierent parts of the mateyal .ha l is,intermittently. The use of endss aprons of leather,rubber, and clothavoids r renders the above disadvantage negligible `.ere the pressure isnot great; but they are 4applicablein cases such as the manufacture ofinlaid linoleums, where the pressure is so great as to require greatstrength and rigidity in the pressing-surfaces. Now I overcome theseobjections by the use of two endless aprons or belts formed of blockshinged together and arranged the one above the other, the adjoiningsides of the two aprons being guided and traveling in the same directionare connected close together by end spacinglinks, and for the purpose ofhaving the junctions between adjoining blocks closed absolutely tightover the parts, inclosing for the time being the material to beconsolidated may be drawn toward each other by a hy-A draulic cylinderon each side. These means are illustrated in the accompanying drawings.

Figure l is a longitudinal elevation and part section on lines A A, B B,and C C of Fig. 2, which is a vertical cross-section to a slightlylargerscale.

A indicates the blocks of the top apron, and

a those of the lower apron.

C and c are respectively the side hinges of the same, the centers of thehinges C being in line with the upper surface of the blocks A. Theadjoining end faces of the blocks A are beveled inward bythe amountnecessary to allow them to pass around the semicircular ends B.

D and d are strong longitudinal guides or slides for guiding theadjoining sides of the two aprons, between which and the inner sides ofthe blocks, respectively, are inserted the antifriction-rollers E and e.These latter are secured together, respectively, and properly spaced bythe side links F andf. The rectangular and semicylindrical side frames GB and b are likewise formed with or as guide-races to receive theantifriction-rollers and guide them around the rest of the frames.

The blocks A a are provided at each side with long half-nuts I and 11,respectively engaging with the screws J and j and usually gearedtogether, so as to move around each apron ata constant uniform speedinthe same direction, though where it is desired to have aslightly-polishing action the speeds of the two aprons may be dierent.If one screw is right and the other left handed, the screws .I and j maybe geared directly together by pinions K and 7o, while if the screws areof the same hand an intermediate Wheel must connect the pinions K and7.: in order that both ICO may advance in the same direction. By hingingthe blocks A, as shown, the surface joints between them are always keptclosed, and by placing the center ot' the semicircular end B in advanceof that of the end b the material m, being fed as shown, does not comeinto contact with the surface of either set of blocks without the jointsof the blocks being quite closed, the material being fed, as shown, witha slight downward inclination. In the same manner. provision is made forthe sheet of material leaving the blocks without comingin contact withany gapping joints between the blocks.

L and Z are strong cross-girders carrying the top frame G B and thebottom slide d, respectively, and these girders are connected togetherby stout bolts fn, cap-pieces O and 0 being inserted between the nuts pand the girders. The whole machine is carried from the side frames R. bymaking the top girders L so much longer than the bottom girders Z thattheir` ends can rest on the top of the side frames R. The nutsp on theends of the bolts 'n are screwed up, so that the adjoining surfaces ofthe apron are at the proper distances apart at the entering and deliveryends, respectively.

It will be evident that racks may be attached to the sides or undersides of the blocks in place of the long half-nuts and the long screwsreplaced by pnions gearing with the racks, also that the screw-bolt andcap connection between the top and bottom crossgirders may be replacedtoward the delivery end by a hydraulic cylinder and piston arrangementfor cases where it is desirable to have the pressure under control. Incertain cases, also, it may be possible or desirable to dispense withone of the aprons of linked blocks A or a, making at the same time thelength of the corresponding antifriction-rollers equal to the full widthof the blocks of the other apron. Lastly, I contemplate also the use ofthe upper series of linked blocks and the means for transmittingpressure through them when traveling along the under side of the upperguides D, in combination with the continuous traveling table, thesubject of application for patent of same date as this present one.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

l. In continuous presses the combination of two series of linked blocksA a having halfnuts I and 't' attached respectively to the sides of theblocks guides or slides D and d held slightly nearer together at one endthan the other rectangular and semicylindrical guideframes G and B and bantifriction-rollers E and e interposed between the blocks A d and theguides or slides I) d and the guide-frames G B and b respectivelyandlongitudinal screws J and j cross-girders L and Z cap-pieces O and obolts n and side frames R all substantially as set forth.
